MemcacheDB

MemcacheDB (pronunciation: mem-cash-dee-bee) is a persistence enabled variant of memcached. MemcacheDB has not been actively maintained since 2009. It is a general-purpose distributed memory caching system often used to speed up dynamic database-driven websites by caching data and objects in memory. It was developed by Steve Chu and Howard Chu.^[1] The main difference between MemcacheDB and memcached is that MemcacheDB has its own key-value database system.^[2] based on Berkeley DB,^[3] so it is meant for persistent storage rather than limited to a non-persistent cache. A version of MemcacheDB using Lightning Memory-Mapped Database (LMDB) is also available,^[4] offering greater performance. MemcacheDB is accessed through the same protocol as memcached, so applications may use any memcached API as a means of accessing a MemcacheDB database.^[5]
